The integrated design of the NXT2005 family (the NXT2003, NXT2004 and NXT2005) combines advanced VSB technology and QAM with the option for Out of Band (OOB) capabilities. The result is a high-performance, lower-cost product designed to operate on reduced power and eliminate the need for multiple components. The chips are built on a foundation of previous NxtWave work on advanced equalizer technology for terrestrial reception.

The chips deliver quality digital signals whether the user is a cable subscriber or receives signals over the air. The NXT2004 includes QAM and deinterleaver memory for unencrypted QAM signal formats. The NXT2003 adds an OOB receiver for unidirectional cable applications to enable the decryption of scrambled signals. The NXT2005 adds a return path modulator to the NXT2003 functions for interactivity.

Micronas has launched its line of 8VSB/QAM/QPSK/NTSC demodulator products, the first line of DTV chips based on its 2004 acquisition of LINX Electronics. Designed for DTVs, set-top-boxes, PCs, DVD records, PVRs and tuner models, the silicon complies with the FCC tuner mandate, which requires CE manufacturers to in

As expected, the major focus of consumer electronics manufacturers at CES this year has been on HDTV displays, recording devices and accessories, not terrestrial DTV tuners. That doesn't mean manufacturers are ignoring over-the-air TV, if only because the FCC has set deadlines for including DTV tuners in sets with scre

LINX Electronics is planning to offer a new version of its chip-level ATSC-compliant DTV reception technology, which delivers DTV reception under multiple ghosting conditions. The technology combines and harmonizes multiple ghosts, turning them into one nearly optimal signal for more increased reception, providing a r

Oren Semiconductor has developed three DTV demodulation chips to receive signals from local broadcast, cable and satellite systems. The ICs, based on Oren's "Cascade" design and DSP core, support any combination of 8-VSB, QAM and NTSC. The OR51122 is an 8-VSB demodulator with a BTSC stereo decoder and NTSC video demod

ATI Technologies, a manufacturer of integrated circuits and cards for 3D graphics and computer displays, recently announced a single-chip solution for plug-and-play ATSC reception. The new IC, the Xilleon 210VC, contains the RF front-end, video decoding and display drivers for ATSC receivers. Supporting the recently a

The NAB and the MSTV filed reply comments on Implementation of Section 304 of the Telecommunications Act of 1996, Commercial Availability of Navigation Devices, and Compatibility Between Cable Systems and Consumer Electronics Equipment.

While U.S. consumer electronics manufacturers have focused on large HDTV sets for terrestrial DTV, elsewhere in the world broadcasters and cellphone operators are working together to bring broadcast TV to the small screen. As reported in the Dec. 15 RF Report , Twinhan Technology Co. in Taiwan is selling a cigarette-p
